bpo-40782: Change asyncio.AbstractEventLoop.run_in_executor to be a method not a coroutine (pythonGH-21852)

jamesba · web-flow · commit 29f84294d88e · 2020-08-17T07:19:46.000-07:00
asyncio.AbstractEventLoop.run_in_executor should be a method that returns an asyncio Future, not an async method.
This matches the concrete implementations, and the documentation better.
